Abstract
Data related to a call is stored to a container in a manner that enables the data to be authenticated. “Container” refers to any type of data structure for storing data, such as a file, database, etc. Thus, a protected container is provided to which captured information relating to a call (e.g., recorded audio of the call, captured application data, captured external data, etc.) is stored. The protected container enables detection of any tampering of the protected data, as well as authentication of such data. A multi-channel recording technique is used to record audio for each outbound channel of a call. Each channel of the audio may be watermarked, and a signature may be generated for use in authenticating the audio data. Information relating to the call (e.g., captured audio, application data, external data, etc.) is captured and streamed into the protected container during the call (i.e., in real time).
